Maxima Function
airy_bi (x)
The Airy function Bi, as defined in Abramowitz and Stegun,
Handbook of Mathematical Functions, Section 10.4,
is the second solution of the Airy equation
diff (y(x), x, 2) - x y(x) = 0.
If the argument x is a real or complex floating point number,
the numerical value of airy_bi is returned when possible.
In other cases the unevaluated expression is returned.
The derivative diff (airy_bi(x), x) is airy_dbi(x).
